Experiment on the Design of an Optical Waveguide Power Divider

Experiment on the Design of an Optical Waveguide Power Divider

To meet the needs of multi-way power distribution applied to high-power solid-state sources, a multi-way power distribution device based on coaxial waveguide is designed and studied. In this work, two dynamically tunable power dividers using waveguide ENZ media are proposed by precisely modulating the internal magnetic field and the widths of the output waveguides. The first approach features a mechanically reconfigurable ring-shaped ENZ waveguide. By analyzing the transmission characteristics of coaxial waveguides and by applying the theory of impedance. In this paper, an E -plane stepped-impedance transformer and Y-junction bifurcation are used to form a waveguide power divider with ceramic substrate loaded with thin film resistors. This structure is realized high isolation in V-band by inserting a ceramic substrate at the H -plane center of the. A numerical model of an equal power divider based on the 4-branch single-mode waveguide is proposed.
